Hello,Thanks for posting your query. The ultrasound report is normal. There are no cysts in the ovaries. Now that the periods have come, there is nothing to worry. The likely cause of delay is due to stress and environmental factors. She does not need the treatment prescribed to her now. She can monitor her cycles and in case this delay in periods happens again, the thyroid hormone evaluation is recommended. Right now she can avoid taking the pills.This delay in periods is not likely to affect her future chances of conception.Hope this answers your query. I will be glad to answer the follow up queries that you have.Please accept my answer in case you do not have further queries.Wishing you good health.Regards.Dr. Rakhi Tayal.
